E-commerce Marketing ideas??

Hi all, Hi all e-commerce experts here. I'm a student who step into the field myself building a site of 50,000 lines of fastCGI Perl and MySQL. Truly appreciate your shared experience. If you are building a site that is way better than pricewatch.com (40 million hits a month- was born in 1995), a bit better price.com and C.Net's hardware devision, then what do you expect (or how popular) after the first month you launch the site? What are the best and economic way to promote your sites: search enginees (of course b/c it's free), which magazines (a site to for dealers to put electronics products and visitors come to compare prices.), which newspapers? I need to really limit expense since I'm a student who open a startup. Clients update my site database themselves by uploading their file through browsers. They update images through ftp by themselves too. Is this price list good: $25 for the first 100 items they put on my site so Net visitors can compare price. $10 for each additional 100 items? If I use the client addresses from pricewatch.com and price.com and many other sites doing similar things to invite (email, mail or call -- which way is prefered??) them to join my services, what do I expect (or what is the percentage of response) from their response within the first month? Million thanks to you. Your help will be appreciated like I see a lake of water in the desert. Best regards, Nam. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
